The Maryland teenager who lapsed into a coma after a rock was thrown through the window of her family's pickup truck on the Capital Beltway returned home for a weekend visit with her family.

Destiny Morris, 15, of Hagerstown, now is speaking and is alert although she still must use a wheelchair, her parents said.

Destiny is undergoing treatment at the Alfred I. Dupont Institute in Wilmington, Del.

She was the person most seriously injured May 27 when three youths threw rocks onto the Beltway in Prince George's County, police said. At least 25 cars were damaged.

Destiny's parents said they have been amazed at the progress of their daughter's recovery. Before she emerged from her coma, doctors had warned them that she was so seriously injured she could die.

"Then they said that even if she did live, she may be in a coma for the rest of her life," said Ellis Morris, her father. "Then she came out of the coma, and {they said} that there was always a possibility different things could be wrong . . . . As it stands now, she's able to see, she's able to speak very softly, she recognizes everybody in the family, and she definitely wanted to come home. She's doing terrific."

Destiny asked to have spaghetti and a vanilla shake during her visit, said Lynn Cline, her mother.

Two 18-year-old men and a 17-year-old juvenile who were arrested in connection with the rock-throwing are awaiting trial.
